Title:
SURFACE-ENHANCED RAMAN SPECTROSCOPY-BASED PHOTOCATALYTIC IN-SITU MONITORING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/098243
Kind Code:
A1
Abstract:
A surface-enhanced Raman spectroscopy-based photocatalytic in-situ monitoring system. The monitoring system comprises: a Raman excitation light source (1), a laser coupling lens (3), a narrow-band filter (4), a total reflector (5), a dichroic mirror (6), a focusing and coupling lens (7), a surface-enhanced Raman scattering optical fiber probe (8), a liquid-phase photocatalytic reactor (9), a photocatalytic light source (15), a Raman collection lens (12) and a spectrometer (14). One end of a common detection portion (80) of the surface-enhanced Raman scattering optical fiber probe (8) separately extends out of a first bifurcation portion (81) and a second bifurcation portion (82). An extension end of the first bifurcation portion (81) is coupled with and connected to the focusing and coupling lens (7). An extension end of the second bifurcation part (82) is coupled with and connected to the photocatalytic light source (15). Another end of the common detection part (80) is disposed in the liquid-phase photocatalytic reactor (9). Raman excitation light and photocatalytic light are transmitted in the same path, which greatly reduces the difficulty of the experiment, and may effectively prevent monitoring errors caused by the incomplete coincidence of focus points, thereby effectively improving the accuracy of Raman dynamic monitoring. The present monitoring system has a compact structure and good portability.
